“How much do I need to retire?” is the most-asked question in personal finance, and the most useless answers are the round numbers — “$1 million,” “$2 million” — thrown around without context. The real answer is personal: it depends on what you spend, when you stop working, and what else (Social Security, pensions, part-time income) fills the gap. This guide gives you the frameworks planners actually use — the 25x rule, the 4% rule, and Fidelity’s salary multiples — with worked examples so you can calculate your own number today.
The 25x Rule: Your Starting Number
The simplest reliable framework: you need roughly 25 times your annual retirement spending saved. Plan to spend $60,000 a year in retirement? Your target is $1.5 million. Spend $40,000? Target $1 million.
The 25x rule comes from the 4% rule, based on the 1998 Trinity study (and decades of follow-up research): a retiree who withdraws 4% of their portfolio in the first year, then adjusts that amount for inflation each year after, has historically not run out of money over 30-year retirements with a balanced stock/bond portfolio. 4% of $1.5 million is $60,000 — hence 25x.
Caveats worth knowing: the 4% rule assumes a 30-year retirement and a roughly 50/50 stock-bond mix. Retire at 55 and you may need 33x (a 3% withdrawal rate) to cover 40 years. It also assumes you rebalance and do not panic-sell in crashes. It is a planning anchor, not a guarantee — but it remains the best simple rule we have.
Worked Examples: Three Spending Levels
$40,000/year spending → $1,000,000 target
A paid-off home in a moderate-cost area, modest lifestyle. Social Security covers a large share (see below) — the portfolio only needs to fill the gap.
$60,000/year spending → $1,500,000 target
The middle-class baseline: some travel, hobbies, helping family, a comfortable but not lavish life in most US cities.
$100,000/year spending → $2,500,000 target
High-cost metro, frequent travel, or supporting adult children. Note how the number scales linearly — lifestyle is the dominant variable, more than investment returns.
Social Security Changes Everything
Your portfolio does not need to cover all your spending — Social Security covers part of it. In 2026, the average retired worker receives about $2,071 per month (roughly $24,850 a year) after the 2.8% cost-of-living adjustment, per the Social Security Administration. The maximum benefit is about $4,152 a month at full retirement age (67) and up to $5,181 at 70 for maximum lifetime earners.
Rework the math: if you need $60,000 a year and Social Security provides $25,000, your portfolio must generate $35,000 — which at 4% means $875,000 saved, not $1.5 million. This is why the “you need $2 million” headlines mislead: they ignore the $25,000-a-year annuity most workers have already earned.
Two Social Security levers matter enormously:
- Claiming age: benefits rise about 8% per year delayed past full retirement age up to 70. The difference between claiming at 62 and 70 can exceed $1,500 a month for life. If you are healthy and can work or bridge the gap, delaying is the highest-return “investment” available to most retirees.
- 35-year earnings record: benefits are computed from your 35 highest-earning years. Years with zero earnings (early career gaps, time out of the workforce) drag the average down — another reason consistent work history pays.
Fidelity’s Salary-Multiple Checkpoints
As a cross-check against the spending-based math, Fidelity’s age-based milestones (assuming retirement at 67): 1x salary by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67. Earning $90,000 at 67 implies roughly $900,000 saved. These two methods should land in the same neighborhood — if they wildly disagree, your assumed spending and your actual income are telling different stories, and spending is the one to trust.
Five Factors That Move Your Number
- Retirement age: every year you delay retirement does triple duty — one more year of saving, one more year of compounding, one fewer year of spending. Retiring at 70 instead of 62 can cut the required savings nearly in half.
- Location: housing is the biggest lever. A paid-off home in a low-tax state versus renting in a coastal metro can shift annual spending by $20,000+ — which moves the 25x target by $500,000.
- Healthcare: the great underestimated cost. Fidelity’s analyses have put lifetime out-of-pocket healthcare costs for a 65-year-old couple well into six figures, and that excludes long-term care. Budget it explicitly; do not assume Medicare covers everything.
- Longevity: a 65-year-old man has roughly a 40% chance of reaching 85; a 65-year-old woman, about 50%. Planning to 90 is prudent for most couples. Underestimating lifespan is the most common retirement planning error.
- Debt at retirement: entering retirement with a mortgage or consumer debt effectively raises your required spending — and therefore your target. The cheapest retirement upgrade is arriving debt-free. Our payoff calculator guide covers the debt side.
Calculate Your Number in 10 Minutes
- Estimate annual retirement spending. Start with current spending, subtract costs that vanish (mortgage if paid off, retirement savings themselves, commuting, payroll taxes), add new ones (healthcare, travel, hobbies). Be honest — most people underestimate by 15–20%.
- Subtract reliable income. Estimate Social Security at ssa.gov (create an account and check your projected benefit at 62, 67, and 70). Subtract any pension or rental income.
- Multiply the gap by 25. That is your portfolio target.
- Compare with where you are. Current savings × expected growth to retirement age vs. the target. If there is a gap, you have three levers: save more, retire later, or spend less in retirement — in that order of pain.
Catch-Up Strategies by Decade
- In your 30s: time is the asset. Max the employer match, automate 15%, invest aggressively. See the age-30 benchmarks.
- In your 40s: peak earning years — direct raises into savings, not lifestyle. This is the decade where the savings rate matters most.
- In your 50s: IRS catch-up contributions kick in (extra amounts allowed in 401(k)s and IRAs from age 50). Audit fees, consolidate stray accounts, and get a real handle on retirement spending.
- In your 60s: decide the claiming strategy, plan the bridge to Social Security and Medicare (which starts at 65), and stress-test the plan against a market crash in the first five years of retirement — sequence-of-returns risk is highest right at the transition.
The Bucket Strategy for Withdrawals
Knowing your number is half the battle; withdrawing it safely is the other half. The popular bucket strategy divides retirement savings by time horizon:
- Bucket 1 (years 1–2): cash and short-term bonds covering two years of spending. You never sell stocks in a crash to buy groceries.
- Bucket 2 (years 3–7): intermediate bonds and conservative funds, refilling bucket 1.
- Bucket 3 (years 8+): stocks for long-term growth, refilling bucket 2 in good years.
In a market crash, you spend from bucket 1 while buckets 2 and 3 recover — which is precisely what the rigid 4% rule cannot do. Studies of dynamic withdrawal strategies show they can sustain meaningfully higher lifetime spending than fixed inflation-adjusted withdrawals, because they avoid selling equities at the worst moments.
Part-Time Work: The Unofficial Fourth Lever
Beyond save more, retire later, and spend less, there is a fourth lever planners increasingly recommend: phased retirement. Working part-time for the first 3–5 years of “retirement” — consulting, seasonal work, monetizing a skill — can add $20,000–$30,000 a year, which directly reduces what the portfolio must generate. Earning $25,000 a year for four years at a 4% withdrawal rate is equivalent to having saved an extra $625,000. For people who like their work (or just like structure), it is the highest-leverage move available — and it delays Social Security, boosting that benefit too.
Sequence of Returns Risk: Why the First Five Years Matter Most
Two retirees with identical savings can have wildly different outcomes depending on when a market crash hits. A 30% crash at 75, after years of withdrawals from a shrunken portfolio, is recoverable; the same crash at 66 — in the first years of retirement, when withdrawals are largest relative to the balance — can permanently impair the plan. This is sequence of returns risk, and it is the strongest argument for entering retirement with that two-year cash buffer (bucket 1) and a flexible withdrawal plan.
Practical defenses: keep 2–3 years of spending in cash/short-term bonds at retirement, be willing to trim discretionary spending after a down year, and consider delaying Social Security as a built-in hedge — every year you delay is an 8% raise on a government-backed, inflation-adjusted annuity, which no portfolio reliably matches.
Don’t Forget the Tax Bridge (55 to 65)
One of the trickiest stretches in US retirement planning is the gap between stopping work and starting Social Security and Medicare: roughly ages 60–70 for many. Retire at 62 and you face up to 8 years of private health insurance (often $1,000+/month for a couple pre-Medicare) plus drawing the portfolio while delaying Social Security to 70. Planners call this the tax bridge: years of low taxable income are ideal for Roth conversions — shifting pre-tax 401(k) money into Roth IRAs at low brackets before required minimum distributions begin at 75. Modeling this window with a planner or good software can save five figures in lifetime taxes.
Frequently Asked Questions
Is $1 million enough to retire?
For many, yes — $1 million at 4% generates $40,000 a year, plus ~$25,000 in average Social Security, totaling ~$65,000. Whether that is “enough” depends entirely on your spending and location. In a low-cost area with a paid-off home, it is comfortable; in San Francisco or New York with rent, it is tight.
What is the 4% rule and is it still valid?
Withdraw 4% in year one of retirement, adjust for inflation annually. Research (Trinity study and updates) shows it survived most 30-year historical periods with balanced portfolios. Critics note today’s high valuations and longer retirements; many planners now suggest 3.5–4% as a range, or dynamic withdrawals that flex with markets.
How does inflation affect my target?
Your target is in today’s dollars unless stated otherwise. At 3% inflation, $60,000 of spending today costs about $108,000 in 20 years. The 4% rule’s inflation adjustments handle this inside retirement — but your savings target must be understood as a future-dollars figure. Online retirement calculators do this conversion for you.
Should I include my home in my retirement number?
Generally no — you need somewhere to live. Count home equity as a backup reserve (downsizing, or a reverse mortgage as a last resort), not as part of the 25x portfolio. The exception: if you firmly plan to sell and relocate to a much cheaper area, the freed equity is real.
The Bottom Line
Your number is 25 times the annual spending your portfolio must cover after Social Security and other income — for most middle-class retirees, that lands between $800,000 and $1.5 million, not the $2–3 million of headline scare stories. Calculate it honestly, revisit it yearly, and remember the three levers: save more, retire later, spend a little less. Time is the most powerful of all — which is why the best day to start was ten years ago, and the second-best day is today. Park the long-term savings in the right accounts — CDs and fixed deposits have a role for the near-retirement years, while growth assets do the heavy lifting decades out.
